Title: Improvements in and relating to winches and the like
IPC: B66D1/20
Filed: 1939-05-08
Abstract: 512,653. Winches. HULLENKREMER, F. May 8, 1939, No. 13695. [Class 78 (v)] In winches, hauling gear &c. having a friction drive comprising a driven friction wheel mounted in rotatable eccentric bearings, the friction wheel being engageable by either a driving friction wheel or by a brake shoe at will, the eccentric bearing is formed of two eccentrics 2, 5 of which one, 5, is rotatable within the other, 2. Each eccentric 2, 5 has a handle 3, 4, by the manipulation of which the driven wheel 13 can be moved away from the driving wheel 7 and into closer contact with a stationary brake shoe 6, in such a way as to prevent shock to the rope or winch. The wheel 13 may be pressed so tightly against the shoe 6 that the load is held, or may be moved away therefrom sufficiently to allow the load to fall gently. The wheel 13 and shoe 6 may be arranged to be always in contact, with greater or less pressure, and the load pull tends to maintain the contact. Duplicate eccentric bearings may be provided at the other end of the driven shaft 9, and these may be moved in unison with the bearings 2, 5, e.g., by coupling together the corresponding handles 3 and 4.

Title: Process for producing purified terephthalic acid
Inventor: OGATA KAZUO
IPC: C07C51/42
Filed: 1963-04-05
Abstract: Purified terephthalic acid is produced by (a) preparing an aqueous solution containing crude alkali metal terephthalate, obtained by the thermal rearrangement reaction of alkali metal salts of aromatic carboxylic acids, and at least 10 weight per cent based on the crude alkali metal terephthalate of alkali metal phthalate; (b) concentrating the aqueous solution by evaporation to separate and recover refined alkali metal terephthalate; and (c) acidifying the latter and separating the free terephthalic acid thus liberated. Preferably, alkali metal phthalate is recovered from the mother liquor obtained in step (b) and is reused as the starting material for the thermal rearrangement reaction of step (a), the acidification (step (c) is effected with phthalic acid or phthalic anhydride in aqueous phase, for example as in Specifications 793,492 and 816,691, and the aqueous solution of alkali metal phthalate obtained thereby is re-used as the alkali metal phthalate for the preparation of the aqueous solution in step (a).  The potassium salts are the preferred salts.  According to another preferred embodiment, carbon dioxide is blown into an aqueous solution of potassium terephthalate, as in Specification 816,248, to produce mono-potassium terephthalate (precipitate) and potassium bicarbonate (in the mother liquor), and then the monopotassium terephthalate is reacted with phthalic acid in an aqueous phase so as to produce terephthalic acid (precipitate and monopotassium phthalate (in the mother liquor), and the potassium bicarbonate is reacted with the mono-potassium phthalate to form potassium phthalate which is re-used in step (a).  Alternatively, the acidification is effected in a first stage in which the potassium terephthalate is reacted with mono-potassium phthalate to form mono-potassium terephthalate and potassium phthalate and a second stage in which the mono-potassium terephthalate is reacted with phthalic acid to form terephthalic acid and mono-potassium phthalate, the latter being re-used in the first stage and the aqueous solution of potassium phthalate being re-used in step (a).

Title: Improvements in or relating to the preparation of 2-keto-l-galactonic acid, its alkali metal salts and methyl ester
IPC: C07H7/027
Filed: 1942-10-06
Abstract: Alkali metal-l-galactonates are subjected to chlorate oxidation in the presence of a vanadium catalyst in a mildly acid medium, and the resulting alkali metal 2-keto-l-galactonates separated by crystallisation.  Crystallised 2-keto-l-galactonic acid may be prepared from the alkali metal salts and may be converted into its methyl ester and brucine salt.  The crystallised salts are suitable for the preparation of ascorbic acid.  In examples: (1) potassium-l-galactonate is treated in aqueous methanol with potassium chlorate in the presence of vanadium pentoxide and orthophosphoric acid, and the excess vanadium oxide removed by filtration; calcium ferrocyanide is added to remove the vanadium in solution and the phosphate, sulphate and calcium ions removed by adding zirconium sulphate, barium acetate and oxalic acid respectively; after filtering and evaporating, potassium-2-keto-l-galactonate is obtained by crystallisation by adding methyl alcohol; (2) sodium-l-galactonate is similarly oxidised with sodium chlorate, but unreacted l-galactonate is removed from the product by adding calcium acetate. The free acid is liberated from the sodium salt by means of sulphuric acid.

Nov. 16, 1917, [Convention date] Mechanical stoking; grates. - An underfeed stoker comprises a longitudinal retort with lateral branch retorts, the green fuel thus being underfed over a greater width than that of the main retort, with consequent increase in the combustion rate. A reciprocating ram 19 feeds the fuel to the retort 27, the bottom of which is formed by a taper tongue 20 forming an extension of the ram and sliding on inclined rails 28. The movement of this tcngue feeds the fuel into the lateral retorts 30 formed between hollow air-supplying walls or draught trunks 32. Thence the fuel passes to inclined grates 31 and dumping-grates 37. The latter are mounted on shafts 38 connected by gearing with a cross-shaft having a pinion engaging a rack 25 secured to the plunger 19, by which means the grates 37 are oscillated; clutches are provided enabling the motion of either grate to be stopped. Air passes from an air chamber 34 to the trunks 32, from which it passes to the fuel through slits 33 arranged fanwise as shown, the upper ones being approximately vertical.
